Senate leaders on Tuesday canceled plans to vote on an Obamacare repeal this week, marking a third straight failure for Majority Leader Mitch McConnell and fellow Republicans who have been unable to fulfill their campaign promise.

"We hope we can move forward and improve health care, not engage in another battle to take it away from people, because they will fail once again if they try", said Sen. Collins, of ME, told reporters that she made her decision despite a phone call from Trump, who's been futilely trying to press unhappy GOP senators to back the measure.

Sen. Lindsey Graham offered a eulogy for the GOP's Obamacare repeal effort on Tuesday, but seized on one bright spot as a reason not to give up after a parade of health care disappointments.

The obstructionists were the Democrats, who all opposed the bill, and Senators John McCain, Lisa Murkowski and Susan Collins. The inability of Graham-Cassidy to accrue enough votes for passage effectively ended the GOP effort to repeal the ACA in 2017. Collins stated that she could not support the health care proposal until it received a Congressional Budget Office (CBO) score, which it would not have before the reconciliation deadline.

Trump's attack was the latest instance in which he's derided fellow Republicans during this year's up-and-mostly-down GOP drive to deliver on their pledge to demolish President Barack Obama's health care law.

In a public statement issued Monday, Collins said she had three major concerns with both the version of Graham-Cassidy under review last week and a new version put together over the weekend, which had promised 43% more federal funding for ME than under Obamacare, according to Becker's Hospital Review. Bob Casey, D-Pa., said he was "relieved that Senate Republicans are abandoning" a vote on an "irresponsible scheme".

One idea - which hardly enjoys widespread support at the moment - is to tie both health care and tax reform to the 2018 budget. He went on to say, "This is not the last chance, this is the best chance" to preserve health care for millions.

The House passed an Obamacare repeal bill in May, but the Senate has now failed three times. "States could also limit specific categories of benefits for Affordable Care Act policies, such as eliminating coverage for mental health or substance abuse treatment". Today, we find out that there is now a fourth version of the Graham-Cassidy proposal, which is as deeply flawed as the previous iterations.

Even as the talk of repeal continued, however, a key Republican committee chairman said late Tuesday that he would seek to resume negotiations with Democrats on a more limited bipartisan package. I believe this is the most important thing I can ever do for the country, working with colleagues, is not to just repeal Obamacare, but to replace it with a system closer to where you live, controlled by people you can vote for. "If we have not produced something on this", he said, Republican voters would punish lawmakers "at the ballot box".
